BROWN, a

" citizen. of the United States, residing in Hamilton, Butler county, Ohio, have invented. certain new and useful Improve ments in Paper-Making Machines, of which the following is a specification. M v

This invention relates to improvements in paper-making machines of the cylinder type employed in making paper'from pulp con-' taining heavy mineral matters of easy precipitation such, for instance, as the pulp employed in making asbestos paper.

The invention will bereadily understood from the following description taken in connection with the accompanying drawings in which: I V

Figure 1 is a transverse section of the machine, in theplane of line 1 of Fig. 4;

Fig. 2. a side elevation of one of the agitators; I

Fig. 3 a plan of one of the agitators; and

Fig. 4 a longitudinal section of the machine in the plane of line 4 of Fig. 1.

In the drawing:

1 and 4 indicate planes of section;

3, the vat;

42, he floor of the vat, the same presenting an upward concavity; and

5, the cylinder-mold mounted for rotation in the vat.

The parts thus far described may be as usual, except as to the concavity of the floor of the vat, and the operation is to be as usual, that is to say, the vat will be supplied with pulp arranged to overflow as usual, the cylinder-mold dipping into the pulp as it rotates, and accumulating a superfioial coating of the pulp which is removed from it, as a sheet, by means of the usual couch-roll. In the ordinary operation of such machines, with the character of pulp which has been referred to, the precipita-- tion of the heavy mineral matters inthe pulp results in the cylinder operating in an imperfect this defect, it has been usual to place agitators in the lower corners of the vat to keep the pulp stirred up.

8, a .crosshead pinned to each of the squared ends of the shaft;

9, a pivot-pin carried by each crosshead at right angles to shaft 6;

10, pivots supported by the vat at each side of the cylinder-mold;

11, suspenderspivoted on the pivots 9 and 12, a shaft disposed through one Wall of the vat, in prolongation of the axis of shaft 6, and adapted to be reciprocated;

12, a connection between shafts 6 and 12- and pivoted to one of the shafts;

13,- a series of crossheads secured to shaft 6;

14, fingers secured to the crossheads 13 and projecting from the crossheads into the space between the concave fi00r4 and the periphery of the cylinder-mold; and

15, tie-bars arranged parallel with shaft 6 and connected with the fingers so that all of the fingers are strengthened or unified so as to move simultaneously when the shaft is reciprocated.

The pulp in' which the cylinder-mold revolves is acted upon by the agitator-fingers fairly close to the cylinder-mold, the result being that the cylinder-mold picks up pulp in a satisfactory" condition, much more so than usual.

The mechanism is readily removed from the vat by first removing the cylinder-mold .and then disconnecting the pivots of the suspenders, and the pivot uniting the two shafts.

I claim: I

1. A papenmaking machine comprising,

a vat, a cylinder-mold adapted to be rotated in the vat, a shaft disposed within the vat below the cylinder-mold, and with its axls parallel with that of the cylinder-mold, sus-.

'penders having pivots at their upper ends supported by the vat and having pivots at their lower ends connected with said shaft, means for, reciprocating said shaft endwise,

and'a series of agitator-fingers projecting sidewise from said shaft at the base of the cylinder-mold, combined substantially as set forth. v

2. A paper-making machine comprising, a vat, a cylinder-mold adapted to be rotated in the vat, a shaft disposed within the vat below. the cylinder-mold and with its axis parallel with that of the cylinder-mold, a

shaft projecting threugh a wall of the vat at one end the first mentioned shaft and adapted to be reciprocated, a pivotal connection between the contiguous ends of the two shafts, suspenders having pivots at their upper ends supported by the vat and having pivots at their lower ends connected with the first mentioned shaft,-a series of crossheads secured to Lthe first mentioned shaft, and agitating-fingers projecting from said ci'ossheads, combined substantially as set forth. v

3. A papenniaking machine comprising, a vat having a concave floor, a cylinder- Inold adapted to be rotated in the vet, a- Shaft disposed Within the vat below the cylinder-mold and with its axis parallel with that of the cy1indei'-nio1d,-a shaft projecting through a Wall of the vat at one end of the first mentioned shaft and adapted to be reeiproceted, a pivotal connection between the contiguous ends of the two shafts, suspenders having pivots at their upper ends su ported the vat and having pivots at thdih lower ends connected. with the first men tioned shaft, a series of cross heads securedto the first mentioned shaft, and agitating fingers projecting from said crossheads,

combined substantially as set forth.

4. A paper-making machine comprising,

a vat, a cylinder-mold mounted to revolve therein, pivots fixed at each side ofjthe vat near the ends thereof, 'a shaft disposed in the vat below the cylinder-mold and shorter than the vat, means for reciprocating said shaft endwise, a crosshead secured to each end of said shaft, pivots carried by said.

crossheads at right angles to said shaft, suspenders detachably pivoted to the first Inelitioned pivots and to the pivots carried by the crossheads, agitator crossheads fast on said shaft, agitating-,i'ingers projecting from the agitating crossheads, and tie-bars secured near the ends of the agitatinglingers,v
